Radiator Core support bushings
 

Looking for some input on these bushings on who's fit correctly....for 1973 car:)

The Bottom ones are same 70-74 and the AMES version are the only correct ones I have seen, so far. Their hardware is way off that comes with it.
Check out a couple videos I made on this subject.
The core support and mounting it 6 min 20 sec >> https://www.youtube.com/watch?v=t9DtbP4ez2A
The mounting hardware > 1 min 53 seconds.. >>>>https://www.youtube.com/watch?v=bHJLaqe-qnQ

Hi Bruce thanks for the info and great videos...awesome...I think I have the old hardware from mine
What's the difference in the two kits Ames offer I wonder, I sent a message so will see, they cover 70-76 ???
FP283
FS771

FP283 is correct, aside from the bolt, the lock washer and the nut, they are NOT correct, or really even usable as the nut will NOT index in the lower subframe. I should have mentioned that in the video.
That said ;, my Next trip Down to Ames I will bring a tiny front frame section, and ask them to pull a 771 kit and discuss the difference and make sure they know what actually works.
NEITHER is correct for 1975 or 76
The '75 and '76 are a much taller unit and the nut has no "imprint" or locator in the subframe. This is because the car has a header panel which sets the distance apart , so it only needs a slight side to side adjustment.
The 771 kit "might" work on a 75 and 76 if you have 3 hands and a buddy to help.

Funny that the '73 had a flanged headed bolt when even the '74 had a hex headed bolt. And you're right on AMK doesn't have one listed.
Washers are listed... https://www.amkproducts.com/search-result/?ser=9781851
